JJC 67mm Variable Star Filter Kit F-STAR67K 4/6/8 Point Adjustable Optical Glass

The JJC 67mm Variable Star Filter Kit (F-STAR67K) is designed to create a starburst effect from point light sources like the sun, light bulbs, or reflective surfaces. The kit includes 4, 6, and 8 point filters, each featuring fine, etched lines on the surface that produce diffraction spikes extending from the light source. This filter is most effective when the light source has a significant contrast from the rest of the image.

Key Features:
- Creates a star effect from point light sources such as the sun, light bulbs, candles, or highly reflective objects.
- Produces four, six, or eight primary diffraction spikes extending from the light source.
- The upper part of the frame features a rotation ring, allowing adjustment of the star effect direction.
- Constructed from high-quality optical glass for clarity and color fidelity, with a durable, lightweight aluminum-alloy frame.
- Compatible with any lens that has a 67mm front filter thread.

Tips for Use:
- The best star effect occurs when the light source is against a darker background.
- Use 8-point filters carefully as many star lines may overpower the image.
- Mid-range or larger apertures are generally sufficient for a good star effect. Always test before critical situations.
